in 1882, looking up certain points for us. Mr. Alex. Wet- 

 more sent a manuscript list of the birds observed by himself 

 and R. B. Rockwell at Palmer Lake, September 5 and 6, 1909, 

 with permission to make any use we desired of it. Dr. 

 Edward C. Schneider of Colorado Coollege was good enough 

 to read over the account of the life zones and give suggestions 

 as to the characteristic plants, while much information was 

 gathered from his "Distribution of Woody Plants in the Pike's 

 Peak Region." Mr. Lloyd L. Shaw has permitted the use of 

 manuscript notes made about Colorado Springs and in Crystal 

 Park as well as the photographs- of the young Sharp-shinned 

 Hawks. Mr. Clark Mellen of New York has kindly given 

 information as to the introduction of game birds at Glen Eyrie. 

 The cuts of the Long-eared Owl, Horned Owl, Burrowing 

 Owl's Nest, Three-toed Woodpeckers, Niglithawk on the 

 ground, the two of the young Magpies and the Magpie's nest, 

 and the two cuts of Cliff Swallow's nests, were loaned by the 

 "Condor," published by the Cooper Ornithological Club of 

 California. 



EXPLANATION. 



The nomenclature of the American Ornithologists' Union 

 has been strictly adhered to in this list, except in the case of the 

 Juncos, where it was departed from for reasons there stated. 



It should be stated that Monument Valley Park, fre- 

 quently mentioned herein, refers to the park of that name in 

 the city of Colorado Springs, and not to Monument Park, some 

 six miles north of the city, and the location of the Woodmen's 

 Sanatorium. 



Whenever the Aiken Collection is mentioned, the collec- 

 tion of birds purchased from C. E. Aiken by General William 

 J. Palmer and presented to Colorado College is referred to. It 

 comprises the results of Aiken's collecting from his arrival in 

 1871 until 1907.
